The velocity of sound will be highest in-

The velocity of sound will be highest in- Correct Answer Steel

Explanation: 

Sound is a mechanical wave that needs a medium to travel.

  • The speed of sound is maximum in solid, then it is in liquid and it is the slowest in gases.
  • The speed of sound remains almost the same for all frequencies in a given medium under the same physical conditions.
  • The speed of the sound depends on the density of the medium through which it is travelling.
  • The particles in the solid medium are closely packed. Hence, the density is high. Information from one molecule to another molecule travels faster in the solid medium.
  • The velocity of sound is highest in steel.
  • In liquid, the molecules are farther apart than in solids. Hence, the density is low for liquids.
  • In gas, the molecules are very loosely dispersed. The speed of the sound wave will be maximum in steel. 

Additional Information

  • The velocity of sound waves in air is 330 m/s. 
  • The velocity of sound waves in steel is 5920 m/s. 
  • The velocity of sound waves in a vacuum is zero. 
  • The velocity of sound waves in water is 1480 m/s.

You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. B: The sound source creates vibrations in the surrounding medium.  C: The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. D: Sound can propagate through a medium such as air, water, and solids as longitudinal waves and also as a transverse wave in solids.
